// By default when you enqueue jQuery in Wordpress you must use jQuery, and $ is not used (this is for compatibility with other libraries).
// Your solution of wrapping it in function will work fine, or you can load jQuery some other way (but that's probably not a good idea in Wordpress).
// If you must use document.ready, you can actually pass $ into the function call: 

// jQuery(function ($) { ... } or this (function($){your code})(jQuery);


// Working method !!!
(function($) {
	
	// $ Works! You can test it with next line if you like
	console.log($);
